Wa 'Alaikum, A'isha was enraged and asked him (Allah's Apostle) whether he had not heard what they had said. He said, I did hear and I retorted to them (and the curse that I invoked upon them would receive response from Allah), but (the curse that they invoked upon us) would not be responded. (Using translation from Muslim 2166)  

أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللهِ يَقُولُ سَلَّمَ نَاسٌ مِنَ الْيَهُودِ عَلَى النَّبِيِّ ﷺ فَقَالُوا السَّامُ عَلَيْكَ يَا أَبَا الْقَاسِمِ فَقَالَ وَعَلَيْكُمْ فَقَالَتْ عَائِشَةُ وَغَضِبَتْ أَلَمْ تَسْمَعْ مَا قَالُوا قَالَ بَلَى قال بَلَى قَدْ سَمِعْتُ فَرَدَدْتُهَا عَلَيْهِمْ إِنَّا نُجَابُ عَلَيْهِمْ وَلَا يُجَابُونَ عَلَيْنَا  

Jabir said, "Some of the Jews greeted the Prophet, may Allah bless him and grant him peace, by saying, 'Poison be upon you (as-Samu 'alaykum)' and the Prophet replied, 'And on you.' 'A'isha, may Allah be pleased with her, said angrily, 'Didn't you hear what they said?' The Prophet replied, 'Yes, and I answered them. What I said about them will be accepted and what they said about me will not be accepted.'"  

أَنَّهُ سَمِعَ جَابِرًا يَقُولُ سَلَّمَ نَاسٌ مِنَ الْيَهُودِ عَلَى النَّبِيِّ ﷺ فَقَالُوا السَّامُ عَلَيْكُمْ قَالَ وَعَلَيْكُمْ فَقَالَتْ عَائِشَةُ رَضِيَ اللَّهُ عَنْهَا وَغَضِبَتْ أَلَمْ تَسْمَعْ مَا قَالُوا؟ قَالَ بَلَى قَدْ سَمِعْتُ فَرَدَدْتُ عَلَيْهِمْ نُجَابُ عَلَيْهِمْ وَلا يُجَابُونَ فِينَا
